CUTTING, FOLDING, AND PASTING MACHINE.

SFECIFIGATION forming part of Letters Patent No. 630,937, dated August15, 1899.

Application filed June 29, 1896. Serial No. 597,325. (No model.) I v ToLLZL w/wm it may ooncer'n:

Be it known that I, EDWARD P. SHELDON, a citizen of the United States,residing at New York, (Brooklyn,) county of Kings, and State of NewYork, have invented certain new and useful Improvements in Cutting,Folding, and Pasting Mechanism, fully described and represented in thefollowing specification and the accompanying drawings, forming a part toof the same.

The object of this invention is the making of a folded productconsisting of a sheet whose sides and ends are each infolded twice inopposite directions onto the same side of its body, preferably, but notnecessarily, equally, and preferably, but not essentially, having theinversely-folded parts more or less overlapped, and, in a modified form,such a sheet with the described side folds omitted.

The invention includes, first, a rotative mechanism consisting of twosets of coacting folding instrumentalities whereby two transverse foldsare imparted to a sheet and a cutting mechanism in such relation theretothat a web is severed transversely and has its front and rearends lappedinwardly or toward each other on the same side of its body; second, incombination therewith a longitudinal folder whereby the sides of saidsheet are primarily infolded upon its body; third, in combination witheither of the foregoing a rotary printing mechanism with the formbearingportions of its form-cylinders so related to the rotative foldingmechanism as to correctly imprint the said sheets, and, fourth, incombination with the rotative folding mechanism of a pasting mechanismwhereby the folded laps may be secured together.

This invention is hereinafter particularly described, aided by oneembodiment of it illustrated by the accompanying drawings, in whichFigure 1 represents a side elevation ofa webprinting machine and itsdelivery apparatus 5 embodying this invention. Fig. 2 is an enlargedside elevation of the delivery apparatus detached from theprinting-machine. Fig. 3 is a plan view of said delivery apparatus asseen looking in the direction of the arrow 2 c in Fig. 5. Fig. i is anend elevation of the delivery apparatus, the delivery-rollers and rotaryfiyand their associated parts being omitted. Fig. 5 is a like endelevation as seen looking in the direction of the arrow 4 in Fig. 6,with the longitudinal folders omitted. Fig. 6 is a vertical sectionalelevation of the delivery apparatus as seen looking in the direction ofthe arrow 3 in Fig. 5, taken through the center of the longitudinalfolders. Figs. 7, S, and 9 are sectional elevations of the ro- 6o taryfolding mechanism, showing the parts in different positions of'theiraction. Fig-1O is a sectional elevation of the final-delivery orsheet-laying mechanism. Fig. 11 is an enlarged elevation of the frontend of the cutting folding-cylinders, showing more particularly the cammotions. Fig. 12 is a similar rear end elevation. Figs. 13 and 14: areelevations of detached cams. Figs. 15 to 19, inelusive, illustrate thelongitudinal folder removed from the machine, Fig. 15 being aperspective view, Fig 16 a side elevation, Fig. 17 the side foldersdetached, Fig. 18 a sectional view of one of them on the section line 13of Fig. 17, and Fig. 19 an end elevation of the folder with its bodybroken away, so as to illustratein section the condition of the foldedmaterial at a point part way of its passage over the folder. Fig. 20 isa perspective view, and Fig. 21a sectional view,of the folded 8oproduct.

It is to be understood that this delivery apparatus is adapted to form apart of any type of printing-machine whereby a web is perfected. For thebetter elucidation of the prescut improvements they are shown in Fig. 1as combined with a web-printing machine of that type known as adouble-ender, in which .the web WV, led from a roll, is guided overrollers and passed between the type 90 cylinder T andimpression-cylinder I, at one end thereof, and thus printed upon oneside is led over a roller and around a V-shaped transferrer andreverser, thence again between the type and impression cylinders, but 5at the other end thereof, whereby it is perfected by being printed onits second side. To prevent offset upon the impression-'cylin der fromthe first printed side of this web, it is accompanied in its secondpassage through the printing-couple by an offset web 0. This perfectedweb (marked XV) is shown as ontering into this delivery apparatus bypassing over a roller 76, which is surmounted by a slitting-disk 20,whereby said web is divided longitudinally into two webs. This deliveryapparatus embodies a pair of longitudinal folders A B, the structure ofwhich is more particularly hereinafter described, a rotary folding andcutting mechanism, the devices of which are carried, respectively, bycylinders D E F, and a sheet-laying device consisting of a rotary fly,said cylinders D E F being of double length, so as to operate uponhalfwebs, into which the main web is divided by said slitter 20, and therotary flies and other parts are duplicated where necessary to act uponthe two products that are formed side by side in the machine. Thisdelivery mechanism is driven at proper speed by means of a verticalcounter-shaft 30, which derives its motion through beveled gears from alongitudinal shaft 31, that is driven from the printing-machine. Theshaft 40 of the cylinder D is driven from said shaft by means of beveledgears 41 42, and on the opposite end of said shaft is carried, outsideof the frame, a wheel 43, which drives a pinion 44 "on the shaft 50 ofthe cylinder E, and this 51 of the cylinder F.

pinion 44 gears with a pinion 45 on the shaft The shaft 51 also carrieswithin the side frame a wheel 52, which meshes with an intermediatewheel 53 on a shaft 54, that carries farther within the side frame apinion 55, which meshes with a wheel 56 on the fly-shaft 57. The shaftalso carries near to the pinion 44 a pinion 46, which drives a pinion 47on the paster-shaft 48, and this shaft 48 through pinions 58 59 andwheels 60 61 revolves the paste fountain disks. The shaft 40 of cylinderD carries within the side frame a wheel 64, which through anintermediate 65 drives the press ing-rollers 80 90, which are gearedtogether by intermeshing pinions 68 69, the pinion 68 gearing with thepinion 65. This wheel 64 also drives the web-roller 76 through a trainof gears 70, 71, 72, 73, 74, and 75. The cylinder F carries at one end awheel 77, which through a pinion 78 drives the pressing-roller 29, andthe delivery-rollers 33 34 are geared together by pinions, only one ofwhich, 79, is shown, and these rollers are driven by means of a pinion81 on the shaft of roller 33, that gears with the intermediate 82 fromthe wheel 77.

The longitudinal folders A B in a general sense are of the typeillustrated and described in Patent No. 383,798. Each consists of ahorizontal plate which is formed to provide three internal guides 35,36, and 37. The guide 35 is formed by the foremost edge of the plate andis of a length equal to the width of that of the ultimatelylongitudinally-folded product, and the guides 36 37 extend rearwardlyfrom the ends of the guide 35, respectively, at angles diverging to therear edge of the plate, where it is of a width equal to that of theoutspread or unfolded web. Of

course these internal guides might be formed by bars, but the platestructure is preferable. The external turners consist of guides 2728,that are inclined obliquely downwardly and forwardly from the internalguide 35, and though closely superposed they are relatively arrangedacross each other at acute angles in the path of the two sides of theweb, so that they operate-to lap the sides of the web that projectoutwardly beyond the ends of the guide 35 successively inward over thecen tral portion of the web and so that the sides thereof are infolded,and preferably so that one side overlaps the other side, and preferablyso as to form three plies of equal extent. These guides, as illustrated,are preferably the inner edges of plates obliquely arranged with respectto the plate forming the internal guides, but might, of course, be bars,if desired. The plate structure for both the internal and externalguides is preferred, because it affords an easy means for securing thesame in position. The cooperation of the three internal guides and thetwo external guides results in folding the web upon two longitudinallines defined at the ends of the guide 35, the guide 27 turning one sideinwardly and the guide 28 turning the opposite side inwardly, thuslapping the web on two parallel lines inwardly, the two sides beinglapped in succession one onto the other in three plies, as is seen inFig. 4, where the folded web W is shown as broken away. It may now beremarked, as is shown in the Patent No. 383,798, that the arrangement ofthese five guides constituting the folder may be such as to lap theouter portions of the web upon one another to a less extent than afolder which will produce three equal laps, as shown, and this laterallapping of the sides may be in such a relation to the central part ofthe web as to cause the side laps simply to meet, and thus form twoplies, or, if desired, it may leave their edges nearly together, but notin contact, according as is preferred. The longitudinally-folded webthus produced has its folds laid in passing between the rolle rs 80 90,preferably spring-seated, which act as fold-laying or pressing rollersand as feeding-rollers. These rollers are geared together by toothedwheels 68 69 and driven by an intermediate 65 from the toothed wheel 64on the shaft of the cylinder D. As only one longitudinal folder has beendescribed, it may be remarked that two folders precisely alike areprovided, so as to operate upon two narrow webs, and that a wide web W,received from the printing-machine, is fed over a roller 76 and slitinto two webs by means of the disk slitter 20, that cooperates with saidroller for that purpose. These two webs are then passed to thelongitudinal folders A and B and are each respectively of a width equalto the rear edges of these folders. Each double longitudinally foldedand lapped web passes from the longitudinal folders to and between thecylinders D E.

IIO

' cadet? The cylinders D E F and their accessories constitute arotating, cutting, and folding apparatus provided with mechanisms thatcapacitate it to cut a web transversely into length and to fold the sametransversely in such manner as to lay the folds toward each other, andit may, and preferably will be, one upon the other, thus producing athree-ply product. The cylinder D is preferably circumferentially twicethe length of the unfolded product to be produced and is provided withci'ltting-blades 10 11, mounted at opposite points in said cylinder, andrearwardly of each of these blades there are provided sheet-impalingpins 3. These pins project through tangentially-arranged guide ways inthe body of cylinder D, and they are respectively pivoted to rock-armsthat are fast to rock-shafts 23, which are springseated, so as tonormally hold the pins protruded from the cylinder (see Fig. 12) andsuitably rocked to withdraw said pins by means of rockarms 16 26, thatcontact with a cam 96, that is held stationary by means of a bracket 97,fixed to the side frame. (See Fig. 3.) This cylinder D is also providedwith tucking-blades 4 5, which are situated diametrically opposite oneanother and circumferentially one-third the distance between thecutting-blades 10 ll in the direction in which said cylinder travels,and these tucking-blades are so secured in sockets in the cylinder D andseated upon springs therein as to be capable of slight circumferentialplay, whereby the changing angular relation of their edges with relationto the nippingjaws 7, carried on the folding-cylinder E, pre vents theiracting as cutting devices upon the fold of the paper, which might resultfrom the shearing action which they would other wise have. The springsare located on the rear side of the tucking-blade, the front side of theblade being considered as that side which is first presented to thenipping-jaws as the cylinder rotates. This location of the springsenables the blade to have a circumferential movement or play as theblade enters between the nipping-jaws. It is essential in order to avoidthe shearing action which it is desired to avoid that the springs belocated on this side of the blade. This cylinder D may, if desired, beprovided with a conductor 99, arranged near its surface, for theguidance of the sheet when detached from the holding-pins. The cylinderE is equal circumferentially to the length of the unfolded product,being of half the size of the cylinder D. This cylinder E is providedwith a cuttingslot 6, formed in a box, as is common, which cutting-slot6 cooperates with the cutting-blades 1O 11, that have elastic sidepieces to hold the paper while being cut, as is usual.

The first-folding mechanism, or folding device, properly so called, toact upon the sheet and by which the first fold therein is produced isthe cylinder E. This cylinder is provided with a fixed nipping-jaw '7and a movable nipping-jaw S. The movable jaw 8 is mounted upon arock-shaft 32 and normally is held closed by means of a spring-rod 84,attachedto its rock-arm 25. This shaft 32 is suit-ably rocked at timelyintervals by means of a cam 63, Figs. at to 12, with which the roll ofthe rock-arm contacts, to open said jaw. WVhen the jaw 8 is open, thepaper is suitably presented to the folding-cylinder E by being tuckedbetween the jaws 7 and S by the tucking-blades a and 5 on the cylinderD. WVhen the paper has been tucked between the jaws, the conformation ofthe cam 63 allows the movable jaw S to be closed by its spring-rod. Thepaper is then seized and firmly held by the jaws and being now under thecontrol of the folding-cylinder is carried onward thereby and the firstfold is formed. After the fold is formed the cam 63 again operates themovable jaw 8 to release the folded paper. This folding-cylinder is alsoprovided with a tucking-blade 12, that reciprocates in a guiding-recessformed through the block in which the cutting-slot 6 is formed and hassuch a range of movement as to clear said slot and provide for itsproper performance of the cutting action and yet be protruded beyond thesurface of cylinder E for performing its tucking operation. Forreciprocating this tucking-blade 12, which normally is held inwardly bymeans of a spring-rod 93, itis provided with a rack 9, that cooperateswith a segment 13, projecting from a shaft 14, suitably rocked by arock-arm 8S, contacting with a fixed cam 39. This cylinder is,furthermore, provided with a paste receiving and applying arm 15, thatprojects from a rock-shaft 86, that has a rock-arm 87, which is actuatedby a fixed cam 24, which encircles the shaft of the carrier 0. Thepaste-applying arm 15 is normally held within the cylinder E andsomewhat within its periphery by means of the spring 85, attached to theshaft 86 and acting to so rotate the shaft as to accomplish thispurpose. Its actuating-cam 24 is so shaped that it projects the arm 15flush with the periphery of the cylinder at suitable times that it mayreceive a film of paste thereon and be then withdrawn within thecylinder E and again be protruded therefrom at the proper time to applythe paste it carries in a spot upon the folded product, as will behereinafter explained. For cooperation with this pastearm 15 in thecylinder E and for the purpose of providing the material for such spotthat is to be deposited upon the product there is arranged in propercooperative position a rotating paster P, the single projecting part 1of which moves in a circular path that enables it to contact with anddeposit paste upon the paste-arm 15,

IlO

which latter operates to transfer the pasteiu a spot on thepartially-folded product. This paster P receives its charge of paste bycontact with a fountain-disk 62, that rotates in a paste-fountain 10 0.After the first fold has been formed iirth paper by the foldingmechanism hereinbefore described and the paste has been applied theretoby the pasting devices the paper passes to the control of the secondfolding mechanism, properly so called, which is the cyl inder F. Thiscylinder F is provided with a fixed nipping-jaw 17 and a movable jaw 18,projecting from a shaft 83, which carries outside the cylinder across-head 19, that has one end attached to a spring-rod 21, whereby thesaid jaw 18 is normally held closed, and which cross-head has a stud orbowl contacting with a cam 98, whereby said jaw is operated at propertimes. Cooperating with this cylinder F for laying the plies of thefolded product together after the fold has been made is thespring-seated pressingroller 29, and beneath this cylinder F and roller29 are situated the delivery-rollers 33 34, which receive the foldedsheet and convey it, guided by the conductors 94, into the recesses abof the r0- tary fiyX and into fixed and Vertically facing slots e of theguides 49. (See Fig. 3.) The recesses a b are cut into the rotary fly insuch a manner that they leave projecting outwardly from them arms ofsuch width as to form propellers acting to thrust the sheet forward fromout of the slots 6 of the guides 49 into the packing-chute 92. The webof paper led from a printing mechanism or other source of supply passesunder the slitter 20, where it is divided into two half-webs, whichrespectively pass over the longitudinal folders A and B, where eachreceives a double longitudinal fold, as hereinbefore described.

It will of course be understood that two halfwidth webs may be fed tothe folding mechanism before described, in which case the slittingdevices will be omitted. It is also to be understood that sheets of theproper length may be fed to the folding devices instead of webs, shouldthis be thought desirable.

As the manipulation of both the webs is the same, a description of theoperation in connection with but one will now be given. The doublelongitudinally-folded web passes from between the pressing andfold-laying rollers 80 90 down to and between the cylinders D E.

Its leading end is caught upon the pin, say 3, and by it the web iscarried around upon the surface of the cylinder D, preferably twothirdsof the length of the product to be made, when the forward end isreleased by the cam operating said pin 3 to withdraw it. taneously orabout simultaneously therewith the tucking-blade 5 will have pressed thebody of the web on a transverse line toward the cylinder E and tuckedthe same within the nip of the spring-seated jaw 8 and its fixedcompanion '7, as in Fig. 6. The cylinders D E continuing to revolve, theweb nipped by the jaws 7 8 will then follow the periphery of thecylinder E, as in Fig. 7, and the first fold will be formed. WVhen thesecylinders have revolved far enough to bring the cutting-blade 10 andcutting-slot 6 into coaction, as in Fig. 7, which will in the illus-Simul-' trated case be at a point rearward of the first fold a distancepreferably equal to one-third the length of the unfolded product, theweb will be severed transversely thereby and the newly-formed end of theWeb will be impaled by the pin 2, and the new leading end of the webthus held will follow the periphery of the cylinder D, as in Fig. 9.When the cylinder E has revolved far enough to lay the forward or firstfolded part of the web upon and next to its surface, as in Fig. 8, thepastearm 15 will be in its outward position, so as to contact with itand deposit its paste in a spot upon the folded lap near to its line offold and about equidistant from its sides. This movement of the cylinderwill have brought the free rearward portion of the now partly-foldedproduct or sheet to that point where the next fold is to be made. Thetucking-blade 12 will now be projected from the folding-cylinder E andwill operate to present the product or sheet to the folding-cylinder E,tuckingit between the jaws 18 17 thereof. This tucking is preferablymade on a transverse liue which is distant from the now rearward edge ofthe sheet by one-third the length of the unfolded sheet or product.Simultaneously with the tucking operation the jaws 7 8 of thefolding-cylinderE release their hold upon the first fold of the sheet,thus leaving the sheet entirely under the control of thefolding-cylinder F. As the folding-cylinder F revolves a second foldwill be formed, after which the folded sheet is presented to thepressing or laying roller 29, and both folds are acted upon thereby.After the edge of the sheet has passed between the cylinder 1F and theroller 29 the jaws 18 17 will be released; but the sheet will of coursecontinue its movement, and the last ply being pressed upon the first oneupon which paste has been previously deposited, as before described, athree-ply product is formed having its front and rearendslaid toward andupon each other and then pasted together. The folded and pasted product,guided by the conductors 94 95 and descending between the cylinder F androller 29, by which it is propelled, as in Fig. 5, will be directed bythe conductors 94 95 into the nip of the delivery-rollers 33 34,

as in Fig. 10. These rollers will deliver the edges of guides e of thepacking-box, where it rests undisturbed until it is displaced and movedstill farther outward by the arrival of the next product. In thisoperation it will be understood that when the leading end of the web hasbeen fed for two-thirds of a sheets length it is then tucked and nippedfor the first fold and when the remaining one-third sheets lengthfollows that the web is severed on the proper cutting-line at the samepointwhere the said firstfold was made,and then while the cylinder E ismaking a further quarter-turn the folding-blade 12 is moved outwardthrough the inwardly-extended cutting-slot and coacts with thenipping-jaws of the cylinder F and stands projected from the peripheryof the said cylinder in proper position so as to make the last fold inthe sheet and is thereafter withdrawn into said slot far enough to leavesaid slot free to act as a cutting-slot for the incoming web in theseverance of another sheet therefrom; also, that when the forward end ofa succeeding sheets length is caught by the pin 2 and is following thecourse of the preceding one the cylinder E will be carrying the firstonce-folded sheet onward to receive its second cross or transverse fold;also, that while the cylinder E is making its revolution and thepasting-arm 15 is approaching the point where the paster P revolves thecam 2% will cause said arm 15 to stand in its forward position, so as toreceive paste from the paster P, and that as soon as this isaccomplished said arm 15 will be withdrawn within the cylinder-face andthere remain until an appropriate time has arrived, such as when thesecond cross-folding action is taking place, when it will again beprotruded in such a position as to apply the spot of paste in the mannerdescribed, so that when the second crossfold is completed the otherwisefree cross-folded laps of the folded product will be fastened togetherlightly just within the outer edge of the second cross-lap. This pastingmay of course be omitted. As here arranged to operate it will beobserved that the actuating-cam 24 is so shaped that the pasting-arm isprojected outward to reoeive its paste. It is then withdrawn and heldwithin the carrier E until the tucking has been effected, is thenprojected far enough to make effective contact with the folded sheet indepositing the spot of paste thereon, is then withdrawn to so pass thecarrier F as not to injure the paper or itself, and then is projected toreceive its charge of paste. The carriers D E F may all be one size andar ranged in a straight line.

While the cutting means may be located between the printing-machine andany folding mechanism or between the longitudinal and rotating foldingmechanism and must be so arranged that the first transverse foldingshall be upon the rearward portion of the sheet, it is preferable toprovide it in the first pair of folding-blade carriers, substantially asherein illustrated.

It will be perceived that since the pasting requisite in the productionofthis product is only a small spot the pasting appliance may bearranged to deposit a spot of paste upon the web at a proper pointbefore it enters the folding mechanism and that a recess in the carrierE may then be provided, so that the paste shall not offset thereon,

which recess in the case where the carrier E also carries thecutting-slot may be in the forward portion of the cutting-box in whichsaid slot is formed; also, that other means for accom plishing thiscombination of pasting the folded product together may be adopted andstill be within this invention.
